Presentation on the topic of the problem of depletion of natural resources. Intensive use of natural resources over several decades leads to depletion of the region's natural resources. There is a change in species. Environmental protection measures

Global environmental problems Destruction of a large number of species of plants and animals Deforestation Rapid reduction in mineral reserves Depletion of the world's oceans as a result of the destruction of living organisms Atmospheric pollution, violation of the ozone layer Pollution of the Earth's surface and disfigurement of natural landscapes Rapid development of industrial enterprises Global warming Rapid population growth

Destruction of a large number of species of plants and animals Many species of plants and animals are disappearing due to the fault of people. In recent years, between 10 and 130 different species are disappearing on Earth every day. This is more than new ones appear. Animals, the number of species of which is sharply declining due to human fault.

Deforestation The process of forest destruction is a pressing problem in many parts of the world, as it affects their environmental, climatic and socio-economic characteristics and reduces the quality of life. Deforestation leads to a decrease in biodiversity, wood reserves, including for industrial use, as well as an increase in the greenhouse effect due to a decrease in the volume of photosynthesis.

Rapid decline in mineral reserves The number of mineral reserves is rapidly decreasing. According to various sources, coal reserves will last for another year, oil for 45 years, gas for 75 years, and iron ore for 65 years.

Depletion of the World Ocean as a result of the destruction of living organisms The World Ocean is depleted as a result of the destruction of living organisms and ceases to be a regulator of natural processes. The depletion of the world's oceans will lead to the depletion of other parts of nature.

Air pollution affects: human health - pulmonary diseases, allergies, cardiovascular, cancer and other diseases are more common in places with polluted air, and the life expectancy of people in such places is shorter. forests, many agricultural plants - when air pollution occurs, they either die or grow much more slowly; materials – the corrosion rate increases.

Destruction of the ozone layer The ozone layer covers the entire globe and is located at altitudes from 10 to 50 km with the maximum ozone concentration at an altitude of km. The saturation of the atmosphere with ozone is constantly changing in any part of the planet, reaching a maximum in the spring in the polar region. The depletion of the ozone layer first attracted the attention of the general public in 1985, when an area with reduced (up to 50%) ozone content, called the “ozone hole,” was discovered above Antarctica.

Pollution of the Earth's surface and disfigurement of natural landscapes It is impossible to find a single square meter of surface on Earth where there are no artificially created elements. Disfigurement of natural landscapes and pollution of the Earth's surface leads to disturbances in the primary structure of the planet, which in turn can lead to various natural disasters.

Rapid development of industrial enterprises Industry does not stand still, it is developing rapidly, and with it the number of industrial enterprises that pollute the atmosphere by releasing wastewater, toxic gases into the atmosphere, etc. is increasing.

Global warming (greenhouse effect) Global warming is a slow and gradual increase in the average temperature on our planet, which is currently observed. Its impact on our planet can lead to the extinction of many species of animals and birds, to the emergence of a greenhouse effect, and quite possibly to the death of humanity.

Rapid population growth Rapid population growth, despite the difficult demographic situation in many countries of the world, has a detrimental effect on the planet as a whole. The number of inhabitants of the Earth is rapidly increasing every year, but at the same time the amount of supplies of clean drinking water, minerals, etc. is sharply decreasing. We can conclude that humanity may disappear from a lack of vital resources.

Some ways to solve environmental problems Widespread use of clean energy sources around the world Freeing ourselves from oil dependence Introducing efficient electricity consumption Developing policies to manage population growth Compliance with the Kyoto agreement to reduce the greenhouse effect Reducing carbon dioxide production at power plants

The concept of “natural resources” and their classification Natural resources are natural objects and phenomena that people use in the labor process. These include: atmospheric air, water, soil, minerals, flora and fauna, solar energy, etc. The main components of natural resources are: Water resources - water reserves used as a source of water supply for industrial and domestic needs, hydropower, as well as transport routes, etc. Land resources - resources used or intended for use in agriculture, for buildings in populated areas, for railways and highways, as well as other structures, for nature reserves, parks, squares, etc., occupied by minerals, etc. Forestry resources - raw materials (used to obtain wood), as well as forests for various purposes - health (sanitary resort), field - and forest protection, water conservation, etc. Mineral resources - all natural components of the lithosphere, used or intended for use in the production of products and services as mineral raw materials in their natural form or after preparation, enrichment and processing (iron, manganese, chromium, lead, etc.) or energy sources.

The concept of “natural resources” and their classification Energy resources are the totality of all types of energy: solar and space, nuclear energy, fuel and energy (in the form of mineral reserves), thermal, hydropower, wind energy, etc. Biological resources are all living environment-forming components of the biosphere with genetic material contained in them. They are sources for people to receive material and spiritual benefits. These include commercial objects (fish stocks in natural and artificial reservoirs), cultivated plants, domestic animals, picturesque landscapes, microorganisms, i.e. This includes plant resources, animal resources (stocks of fur-bearing animals in natural conditions; stocks reproduced under artificial conditions), etc.

The concept of “natural resources” and their classification All natural resources are divided into two groups: exhaustible and inexhaustible. Exhaustible resources are those, the volume of which can be determined and limited with a certain degree of accuracy, the reserves of which, as they are exploited, have decreased to such an extent that their further exploitation threatens their complete disappearance. As a result, depletion of natural resources inevitably occurs. In turn, exhaustible resources are divided into renewable and non-renewable natural resources. Renewable natural resources include those that can be restored either by the forces of nature themselves (naturally) or with the help of purposeful human activity, but only if the conditions and rate of restoration for this are maintained. Renewable resources usually include: land (elements of soil fertility), water (fresh underground water in the zone of active water exchange) and biological (forests, natural feeding grounds, land, aquatic fauna, flora and fauna, etc.). Inexhaustible natural resources are divided into: space, climate and water. This is the energy of solar radiation, sea waves, and wind. Taking into account the huge mass of air and water on the planet, atmospheric air and water are considered inexhaustible. Selection is relative. For example, fresh water can be considered a finite resource, since acute water shortages have arisen in many regions of the globe.

Environmental measures Currently, the Federal Target Program “Waste” is being implemented, the task of which is to reduce the level of environmental pollution from waste and save natural resources through the maximum possible recycling of waste into economic circulation. The program includes tasks to reduce the volume of their formation through the introduction of low-waste and non-waste technologies, reducing the amount of hazardous production residues through the use of new technologies, as well as tasks for their environmentally safe disposal. Despite some progress in the field of environmental protection in general and in waste management in particular, the situation on this issue in Russia, compared to many developed countries of the world, remains tense. Only 3.5% of solid household waste is processed industrially, and the rest is transported to landfills and landfills. Until now, in Russia there is a negligible number of enterprises for the neutralization and disposal of toxic industrial waste that meet the necessary requirements, and practically no equipment is produced for these purposes. If urgent measures are not taken, Russia may turn into a “waste dump.”

Ways to solve a global problem For example, Italy proposed using new types of building materials in cities: “transparent concrete”, air purifying paint (it “absorbs” smog) and antibacterial ceramic tiles. The Finnish Pavilion was designed to minimize CO2 emissions as much as possible (in other words, to ensure that the greenhouse gases it creates are captured and used). In the case of Malaysia, the building material for the facade was recycled plastic, as well as material based on recycled palm oil. Norway used translucent material for the roof - a special type of artificial leather. In addition to transmitting light during the day, this material accumulates solar energy - and the pavilion can provide itself with energy independently, completely autonomously from the general power grid.

The work can be used for lessons and reports on the subject "Ecology"

Ecology is a science that studies the relationships between humans, animals, plants and microorganisms among themselves and with the environment. Presentations and reports on Ecology will help in the study of this wonderful science.

Depletion of WATER resources

We came to meet you today,

To talk again about the problems of the Earth.

Let everyone hear us, and of course understand,

And they will quickly move on to useful things.

Water resources– water reserves used as a source of water supply for industrial and domestic needs, hydropower.

I don't want the river to dry up

Where so many goldfish splash,

Where the boat dances briskly at the pier,

Where the warm evening is sometimes so quiet!

Let the rivers on earth not die,

Let misfortune pass them by,

Let them remain pure forever

Cold and tasty water.

Water is the most common chemical compound on the surface of the Earth and at the same time the most amazing.

97% are seas and oceans

Fresh water reserves in the world are about 3% of the total amount of water.

BUT only 1% of the water on the planet is suitable for drinking.

Why, with such a huge amount of water, does a person worry about its shortage?

Water is the source of life and all living things.

Almost all life on earth cannot do without water.

Animal trails in the forest lead to a watering hole.

Birds fly to rivers and lakes.

People have long chosen a place near the water, settling along the banks of rivers and lakes, where there was plenty to drink.

Water is the source of life and all living things.

One of the reasons for the decline in fresh water reserves is a decrease in the water flow of rivers associated with deforestation along their banks.

But, perhaps, the main reason for the shortage of fresh water on Earth is its pollution.

Over thousands of years, people have become accustomed to water pollution and, unnatural as it may seem, dumped dirt and sewage into the places where they got their drinking water from.

in front of you. Chests of gold, precious stones, money from those times - everything belongs to you. But there is not a drop of fresh water around, and all the gold in the world is not needed -

but to you. A glass of ordinary water will become more valuable to you than the countless riches of the whole world.

Water is the source of life and all living things.

Imagine that the seas and rivers have dried to the bottom, and that’s it

the treasures that the sea hid from man appeared

in front of you. Chests of gold, precious stones, money from those times - everything belongs to you. But there is not a drop of fresh water around, and all the gold in the world is not

you need it. A glass of ordinary water will become more valuable to you than the countless riches of the whole world.

By 2050, 30% of the world's population may face a shortage of drinking water.

• The minimum amount of water a person needs to survive is 0.5 liters of water per day.
• The required amount of water for a person is 2 liters per day.

How do we use the water we borrow from nature?

Showering for 5 minutes - 100 l

Bath filling - 200 l

Washing machine (1 cycle) - 150 l

Single flush in the toilet - 8 – 10 l

Average water tap consumption - 15 liters per minute

Do you know that …

• Russia's first law on water protection was written by Peter I;
• an average-weight human body contains about 5 buckets of water;
• without water there is no life, not a single spore, not a single seed will germinate or develop;

Without water there is no rotting and decomposition of plant and animal organisms;

Without water, sugar, starch, fats, acids and other substances cannot form in a green leaf;

Water is a perpetual motion machine of living and dead nature; water moves, regulates the temperature of climatic zones and determines climatic zones.

SAVE WATER!

Water is the source of life

and all living things.

Every person who carefully and wisely uses the resources of nature helps to preserve the environment for themselves and future ones.

generations

We live in the same family,

We live in the same circle,

Walk in the same line

Fly on the same flight...

Let's save

Chamomile in the meadow

Water lily on the river

And cranberries in the swamp...

Man, having created culture, nevertheless did not free himself from the bonds that connect him with nature. But the development of technology and the active use of natural resources had such a strong impact on the Earth’s ecosystems in the 20th century that it forced people to think about rational environmental management not for the sake of profit, but for the sake of survival. During the lesson, you will remember the classification of natural resources, learn about the main problems associated with their use, and the history of environmental management in prehistoric and historical times. Get acquainted with modern ideas about the rational use of natural resources.
